Visual c++ 使用DirectShow从麦克风将音频捕获到文件（音频录制器WAV Dest'；的任何替代方案）

参考：http://www.codeproject.com/KB/audio-video/cacsave.aspx？msg=3094764#xx3094764xx

我找不到像“录音机WAV Dest”这样的东西。在我的电脑中，Graphidit显示了以下内容：（与第1部分相关的n工作得很好。）

在几乎所有的windows PC中，哪一个是保存wave文件的常用名称。目前，对于WinXPSP2+

Wav dest是一个示例，您可以从SDK附带的DirectShow示例中编译。你可以编译并注册它

它确实受到围绕2gig wave文件限制的限制（这对我使用64通道音频来说是个大问题）。我发现使用AVI Mux过滤器（CLSID_AviDest）是绕过wave文件格式限制的一种很好的方法。

顺便说一句，AVI的文件大小限制如下well@RomanR. 某种程度上。很久以前，AVIs引入了一种允许RIFF格式的多个AVI数据块的方法。也就是说RIFF头的大小将是错误的。。。但是你仍然可以通过正常跳转来导航。MSDN说，事实上AVI Mux可以创建大于1GB的AVI。问题是它遇到了另一个问题，达到2（或4 GB，不确定），并且更大的文件无法播放（）。如果需要使用原始音频的大文件，我会研究MP4和MKV容器@romar。真正地我知道FAT32将文件限制为4GB，但我认为上面的扩展名（看起来是AVI2）基本上只限制文件系统的最大大小。NTFS大约是16 EB。2GB问题的一个更好的链接：注意“在一个看似成功的AVI文件写入之后，导致AVI文件损坏…”然后“…如果你想使用这种格式，你需要编写你自己的mux…”-这与我的记忆相匹配，2+GB的文件被破坏。
